Still working on my TR86. Have to replace or rebuild the covers that go over the rotors. NH want's about a grand for each. Anyone else replace or rebuild them. Local machine shop can roll the concavity but can't put the bends along the sides and claims you can't weld on an angle iron 'cause it will warp. Did find one shop that can do it but looking at other options. Need to replace the sprockets on the rotor drives too. Worn pretty badly and looks like sprocket and shaft are all one piece... not a good idea! Any help appreciated.

Yeah, those sprockets and shafts are all together. Not a great idea, as you said. Possibly you could get a machine shop to cut them off and put different ones on. Probably cheaper than new shafts -I would pretty much guarantee it. You could probably go to heavier chain then too if you wanted to get the rotor side done in the same manner.

Rotor covers. We did those on our TR98 and they aren't cheap. I wouldn't go for the Hi wear ones, because they weren't all that longer wearing than the regular ones. The problem I think is that there isn't enough clearance between the rotor and the covers, which causes it to wear more. The CRs have been changed in this, but that sure doesn't help you at all!

I would think that a machine shop should be able to do the bending on it. Maybe even just tack the vanes in and weld them up after its in the machine. That might be an option.

Had the local weld shop look at the covers and they can't curve them and put the lips where the bolts go through so they called a shop about 50 miles away who can. They NH's replacements are $990 while the fabricated ones will cost $400 for time and materials to add vanes, drill holes, etc. So the total on the fab's would be about $700 plus fuel to drop off and then return to get the new ones. Checkin at bone yard too. Hopefully they have good ones there. Might get lucky and find a burnt machine with very little wear and no rocks through her.
